huge-wave

so I’m almost 100% sure I don’t have anxiety, I’m really loud and outgoing and I’m almost never shy. but sometimes I randomly get these huge waves of uncomfortableness and it makes me feel really awful and I don’t know what it could be? it just happens randomly a few times a week and no matter what im doing or who im with or if im having fun it just happens and I don’t know what it means or how to make it stop. and when it happens I dont want to look at anyone or talk to anyone and I don’t want anyone to try making me feel better because it just ends up making it feel more uncomfortable
